The Recommended Reading Order
To experience the full journey of Hiccup Horrendous Haddock III, you should read the main series in publication order. Although the first few books feel like standalone, episodic adventures, the series eventually builds a continuous narrative arc. Starting around Book 9, the plot becomes highly serialized, leading directly into a high-stakes final trilogy. Reading the books out of order will lead to major spoilers regarding character fates, the rising dragon rebellion, and Hiccup's growth from an underdog misfit into a legendary leader.
The 12 Main Novels in Order

Prequels, Novellas, and Companion Guides
Beyond the core 12-book series, Cressida Cowell has written several companion pieces and prequels that expand the lore of the Barbaric Archipelago. Here is how they fit into the reading order:
- Hiccup the Seasick Viking / How to Be a Viking (1999): This is the original picture book written and illustrated by Cressida Cowell before she expanded the concept into the chapter books. It features a younger, seasick Hiccup who must prove himself during a storm. It functions as a proto-version of the main story and can be read first as a fun curiosity, or skipped since it occupies a slightly different continuity.
- The Day of the Dreader (2012): Originally written for World Book Day, this short story is set chronologically between Book 7 (How to Ride a Dragon's Storm) and Book 8 (How to Break a Dragon's Heart), making it Book 7.5. It tells the story of the Hairy Hooligans facing off against a terrifying dragon called the Dreader during an unusual heatwave.
- The Incomplete Book of Dragons (2014) / The Complete Book of Dragons (2014): This is an in-universe guide written by Hiccup himself. It catalogs the various dragon species, their behaviors, stats, and abilities. It is best read after Book 11 or 12, as it references many dragons encountered throughout the entire journey.
The Movie Tie-in Books (The Hidden World)
In 2019, several books were published to accompany the third DreamWorks animated movie, How to Train Your Dragon: The Hidden World. These include titles like World of Dragons, Journey to New Berk, Meet the New Dragons, The Night Fury and the Light Fury, and Homecoming. These are not written by Cressida Cowell and do not belong to the literary universe. They are tie-in books based on the movie continuity and should be read separately from the main novels.
Key Differences: The Books vs. The Movies
If you are approaching the books after watching the DreamWorks movies, you should prepare for some major differences. The movies are a very loose adaptation of the source material, sharing only character names and the general Viking setting:
- Toothless's Size and Nature: In the movies, Toothless is a sleek, black, horse-sized Night Fury that Hiccup can ride. In the books, Toothless is a tiny, green Common or Garden dragon who has no teeth at first, fits on Hiccup's shoulder, and is incredibly lazy, disobedient, and demanding.
- Communication: In the books, Hiccup has a rare ability: he can speak and understand "Dragonese," the native language of the dragons. This allows him to converse directly with Toothless and other dragons. In the films, dragons do not talk, and their bond is communicated through body language.
- Astrid vs. Camicazi: The film's primary female lead, Astrid Hofferson, does not exist in the books. Instead, Hiccup's close female companion is Camicazi, the fierce, blonde heir of the Bog Burglar tribe. Unlike the romantic relationship between Hiccup and Astrid in the movies, Hiccup and Camicazi share a purely platonic friendship.
- Viking Culture and Dragon Training: In the books, Vikings have already "trained" dragons for generations, but they do so by shouting at them and keeping them as working pets or hunting tools. Hiccup's approach of speaking to them and treating them with kindness is seen as weird. In the movies, the Vikings are at war with dragons until Hiccup shows them how to build relationships with them.
What to Know Before You Start
Cressida Cowell's series starts out as a humorous, episodic children's adventure, filled with doodles, exaggerated Viking names, and toilet humor. However, as the books progress, the overarching plot becomes significantly darker, more complex, and deeply emotional. By the time you reach the final trilogy (starting with Book 9), the series matures into an epic high fantasy war story that deals with themes of prejudice, leadership, freedom, and the cost of peace. Don't let the silly tone of the first few books fool you; this series delivers one of the most rewarding and complete character arcs in children's literature.
